Schwarf ac810a105c mathext: optimize Li2 and add benchmarks

This optimizes the complex dilogarithm Li2 using targeted mappings
(reflection/inversion), a real-axis fast path, and a Bernoulli-in-x
expansion (x = -log(1 - z)), inspired by this Rust implementation[1]
(and references therein). The exported API remains unchanged, and
runtime improvements are measured by an added BenchmarkLi2.

Performance improvements range from a few percent to large factors,
depending on the region of the complex plane.
